Abstract

The present study was undertaken to gain information on the nature and magnitude of genetic variability, heritability and genetic advance existing for various quality traits in cherry tomato. Ten diverse lines of cherry tomato were crossed in diallel fashion (excluding reciprocals) and evaluated for genetic variability studies in protected conditions. The experimental findings revealed that the phenotypic variation and the genotypic variation was equal in magnitude for all the traits indicating the less influence of environment on all these traits. High PCV, GCV and genetic advance as percent mean was observed for dry matter content (%), titratable acidity (%) and lycopene content (mg100g −1), indicating the additive genetic effect. Phenotypic selection for their improvement could be achieved by simple selection.
